At Gamescom a few weeks ago, I got to spend about an hour and a half across a couple of days with Rotterdam, one of the two maps playable in the Battlefield 5 open beta. With the typical lack of co-ordination that you get at public events, it was a total mess. To make matters worse, Rotterdam is a dense, highly exposed map, with lots of long sight lines and exposure on most parts of the map.
Narvik is the other map playable in the BF5 open beta. Thankfully, it's a much better showcase of DICE's grand shooter.
